Draft for Kubernetes is a tool that helps developers quickly prototype microservices and expose them on a publicly available domain. It utilizes Docker, Helm, and Kubernetes Ingress Controllers to make applications publicly available in a hurry. Draft generates a generic Dockerfile and helm chart for the application, creating an ingress resource to expose it at a URL. To use Draft, you need a Kubernetes cluster, a domain name, an account on quay.io or hub.docker, a working Helm installation, and a golang development environment. The tool supports basic python, ruby, php, node, and java applications. After installing the dependencies and creating a sample application, users can run the `draft init` command to set up Draft, which spins up a deployment and some draft pods in the kube-system namespace. Once set up, users can use Draft to create their application by running the `draft create` command, which scaffolds out the helm chart and Dockerfile, as well as creates a draft.toml file that controls different environments for the application. The final step is to run `draft up`, which builds the Docker image, pushes it to the configured container registry, runs Helm install on the preconfigured helm chart, and deploys the application to Kubernetes. Draft provides a way to quickly iterate on things like webhooks or APIs by rebuilding the image and pushing changes live with a single command.
